aSince on both tests data were the same (below average on test 1 and below average on test 2), this shows positive association and since all students were like that, the QOR for this situation is 1.

bSince on data here is almost similar to that of the first one with some outliers, the QOR for this situation may be close to 1, and among the choices that is 0.81.

cSince data shows no correlation at all, this means on the scatterplot that there are even numbers for both Quadrants J and III and Quadrants II and IV, this means that the QCR is 0.

dSince data shows alternate results for tests 1 and 2 (below average students on test 1 now above average on test 2, which means as there are low values on test 1 and high values on test 2), this must mean that this has a negative association. Hence, QCR is at —1.

eSince there were almost the sameamount of students who were above average to below average, then this must mean in the scatterplot, there are almost the same number of points in Qs I and III to Qs II and IV with the former having a few more points, then this must mean the QCR for this situation is close to 0, and among the choices, this is 0.33
